Answer 1

jetzt Telefon Auth ist in firebase.Here ist-Code für Telefon Auth Firebase mit:

EditText phoneNum,Code;   //// two edit text one for enter phone number other for enter OTP code 
Button sent_,Verify;     // sent_ button to request for verification and verify is for to verify code 
private PhoneAuthProvider.ForceResendingToken mResendToken; 
private PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks; 
private FirebaseAuth mAuth; 
private String mVerificationId; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_phone_number_auth); 

    phoneNum =(EditText) findViewById(R.id.fn_num); 
    Code =(EditText) findViewById(R.id.code); 

    sent_ =(Button)findViewById(R.id.sent_nu); 
    Verify =(Button)findViewById(R.id.verify); 

    callback_verificvation();         




    mAuth = FirebaseAuth.getInstance(); 



    sent_.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String num=phoneNum.getText().toString(); 
      startPhoneNumberVerification(num);     // call function for receive OTP 6 digit code 
     } 
    }); 





    Verify.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String code=Code.getText().toString(); 
      verifyPhoneNumberWithCode(mVerificationId,code);     //call function for verify code 

     } 
    }); 
} 







private void startPhoneNumberVerification(String phoneNumber) { 
    // [START start_phone_auth] 
    PhoneAuthProvider.getInstance().verifyPhoneNumber(
      phoneNumber,  // Phone number to verify 
      60,     // Timeout duration 
      TimeUnit.SECONDS, // Unit of timeout 
      this,    // Activity (for callback binding) 
      mCallbacks);  // OnVerificationStateChangedCallbacks 
    // [END start_phone_auth] 


} 







private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) { 
    mAuth.signInWithCredential(credential) 
      .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { 
       @Override 
       public void onComplete(@NonNull Task<AuthResult> task) { 
        if (task.isSuccessful()) { 
         // Sign in success, update UI with the signed-in user's information 

         FirebaseUser user = task.getResult().getUser(); 
         Toast.makeText(getApplicationContext(), "sign in successfull", Toast.LENGTH_SHORT).show(); 
         // [START_EXCLUDE] 

         // [END_EXCLUDE] 
        } else { 
         // Sign in failed, display a message and update the UI 

         if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) { 
          // The verification code entered was invalid 
          // [START_EXCLUDE silent] 

          // [END_EXCLUDE] 
         } 
         // [START_EXCLUDE silent] 
         // Update UI 

         // [END_EXCLUDE] 
        } 
       } 
      }); 
} 






private void verifyPhoneNumberWithCode(String verificationId, String code) { 
    // [START verify_with_code] 
    PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId, code); 
    // [END verify_with_code] 
    signInWithPhoneAuthCredential(credential); 
} 










private void callback_verificvation() { 

    mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() { 

     @Override 
     public void onVerificationCompleted(PhoneAuthCredential credential) { 

      signInWithPhoneAuthCredential(credential); 
     } 

     @Override 
     public void onVerificationFailed(FirebaseException e) { 
      // This callback is invoked in an invalid request for verification is made, 

     } 

     @Override 
     public void onCodeSent(String verificationId, 
           PhoneAuthProvider.ForceResendingToken token) { 
      // The SMS verification code has been sent to the provided phone number, we 
      // now need to ask the user to enter the code and then construct a credential 
      // by combining the code with a verification ID. 


      // Save verification ID and resending token so we can use them later 
      mVerificationId = verificationId; 
      mResendToken = token; 

     } 
    };
